For example, humans have an exceptionally high proportion of fertilised eggs that have the wrong number of chromosomes and one of the highest rates of harmful genetic mutation.

Researchers identified an unusual genetic mutation in orange domestic cats that has not been found in any other animal, according to a new study.

Researchers found the gene and genetic variation behind orange fur in most domestic cats, solving a decades-long mystery.

A Stanford-led study has identified a mutation on the X chromosome that causes orange fur in cats. The mutation switches on the normally silent <i>Arhgap36</i> gene in pigment cells, blocking ...

An advanced genomic analysis of a multigenerational family is providing new knowledge about genetic mutations and their transmission, both the variants that are inherited and those that arise anew.

In males, who only have one X chromosome, a mutation in the gene causes the condition while in females who have two X chromosomes, mutation has to occur on both X chromosomes to be affected.

Scientists at UC San Diego find that gene expression is linked to gene mutations and may be caused by them. That could make efforts to slow the aging process a lot more challenging.

X chromosome mutations can cause intellectual disability, and the X chromosome is thought to be crucial to brain health. Since many genes that are related to the brain are on the X chromosome, the ...

Translocations are when chromosomes break and the pieces attach to different chromosomes. Learn about the disorders caused by this genetic reassortment.

X-chromosome inactivation may reduce autism risk In mice, the pattern of X-chromosome inactivation in female brains altered the effect of a mutation linked to the disorder. Peer-Reviewed ...
